I have a red wire and a purple under one terminal. The purple was going to the coil and the red was going to the choke. The other side of the resistor has nothing on it and I believe that's why my coil is burning up so often. Where should the other wire go on the resistor? To the alternator? Or the starter selinoid? Thanks for the reply by the way!

The resistor isn't for the coil, it's for the points. They don't live long with 12V on them, so they put the resistor on it to decrease the current.

Get your dvom out and see what voltage you have on the red/ purple wires.

In your case the RED wire same as choke goes on one side terminal but you need some sort of 12v input to resistor, and the Purple wire on the other terminal that goes to the positive coil.

One this diagram what is the jumper wire for on the resister it says for El , and do I need that green wire from resister to alternator also? It currently doesn't have one.

Doesn't have a wire, or doesn't have a green wire? The color doesn't matter as much as whether it has a wire. If you see a red wire (or orange) AND a purple wire, the purple wire does what the green wire does, except that it goes through the ignition key.

The EI jumper is used when you have an internally resisted coil. I believe the internally resisted coils are 3 ohm and the coils that use a ballast resistor are 1.5 ohm. You don't want to run a 1.5 ohm coil very long without a ballast resistor. Sometimes there is a bypass for full voltage when the starter is engaged, but that would be it.
